Letters Patent No, 103,300, dated May 24, 1870.

IMPROVEMENT IN DRINKING-TUBES FOR INVALIDS.

a v i The Schedule referred to in these Letters Patent and making part of the same,

I and to the letters of reference marked thereon.

The object; of this invention is to produce a simple and economical drinking-tube for theuse of invalids;

and

The nature of this invention consists in modifiing or improving the device for attaching the tube to a i'essel containing the proper fluid for drink or use, hereiuat'ter to be more fully described.

To enable those herein skilled to make and use my said invention, I will now more fully describe the same.

Figure 1 reprcscpts a perspective view, showing the attachment of my improved tube by nicans of a clamp spring, and i Figurcfl rcprcscntsa perspective view of the same,

attached to the sides of a vessel by means of the double-coil spring attachment.

I employ a rubber or other flexible tube, A, arranged with a suitable mouth-piece, 1i.

' At the supply-end of the tube the same is connected with the influent pipe 0. Said pipe, though usually made otmetal, may also be made of wood, rubber, or glass material.

- Said pipe has a closed bottom, 0, and side inle't-openings v. V i v lnordcr to prevent the inflow of sediment or impurities, said openings c are arranged somewhat above the bottom-end c, ascicarlyshown in fig. 1.

Securely connected near the top of the iuiluent pipe is the clamping spring D, of the form shownju the figures.

It is plain that, when the influent pipe is put. into the vessel containing the necessary fluid, the end (I of the spring-D acts as a clamp to securely adjust the same to the sides of the vessel, thus retaining the ii) fluent pipe in the vertical positiourequircd for use.

Whcu the pipe D' is made of glass, the metallic spring I) n'ot'bcing used in 'its'stead, the double-coil spring E is arranged in connection with the pipe.

Said double-coil springhas a smaller vertical coil, 0, winding about the influeut pipe, the pressure of the coil being suiiicicnt to support the entire spring with relation to the iniiucnt pipe, to any height required.

The larger horizontal coil 0' will grip upon the sides of the fluid vessel, and thus, while forming a secure support so long as required, may readily oe drawn oit vertically from its engagement on the vessel.

.1 am well aware that, there are many other devices which could be made to answer the purpose of this invention, but thatconsistiug of the spring clamp is deemed by me the most important; and I, therefin-e,

here disclaim all others.

Having thus fully described in said invention,

What I claim is-- The iniluent pipe 0, :o-rangml'with the clamp spring I) rl,substautiaiiy a and for the purpose set forth.

In tcstinion' :5; and invention, I have hereunto set my hand in presence of witnesses.
